i can get the macbook air 2018 16 gb/512 gb new for 1500usd. Do I go for it or wait for macbook 12 to get an update? Like the looks and size of the macbook 12. If the air had quadcore i’d be a lot happier. Right now, i have the 2018 mbp touchbar 15 inch high end, which I want to leave at home. The secondary computer will also be used for software development. Thanks!
